Place melted butter in a medium sized bowl. Add in the white sugar, brown sugar, dry oatmeal packets and salt and mix until combined. Stir in vanilla and eggs until combined.

Cover bowl with plastic wrap and refrigerate for 30 minutes.

Preheat oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper or a silicon mat.

Scoop chilled dough with a round tablespoon measure or small cookie scoop onto lined baking about 3 inches apart. (Flatten slightly with the back of scoop, if you desire an extra thin cookie.)

Bake for 9 to 12 minutes, until the edges are golden brown. Allow cookies to cool on the pan for 5 minutes (they will continue to cook a bit). Use an offset spatula to transfer to a cooling rack to cool completely.
